Question

Ethyl bromide reacts with silver nitrite to form.

• A. Nitroethane
• B. Nitroethane and ethyl nitrite
• C. Ethyl nitrite
• D. Ethane

Answer 1

Answer: (A)

Nitroethane

Answer 2

$C_{2}H_{5}Br + Ag - O - N = O \rightarrow \underset{\text{Nitro ethane}}{C_{2}H_{5} - N\begin{matrix} O \\ O \end{matrix}} + AgBr$

$Ag - O - N = O$ is a covalent compound. Therefore, attack of nucleophile occurs through Nitrogen atom. Hence, nitroethane is formed.
